AI Aurora Carter found the first standing stone by nearly walking into it.
It rose out of the dark like a shoulder, black and wet with moonlight, its surface ridged like old bark though it was stone, not oak, not anything sensible. She stopped with one trainer half sunk in the sodden grass and let her breath out through her nose. The air steamed pale in front of her.
“Brilliant,” she muttered. “Ancient boundary marker. Very normal. Definitely where you want to be after midnight.”
Her voice did not carry properly. Richmond Park should have taken it, softened it among the trees, given it back as a small human sound beneath the vastness of night. Instead the word normal seemed to drop straight down at her feet, dead on arrival.
Rory tightened her grip on the torch.
The beam jittered once, snagging on low bracken, glistening roots, the silver line of a spiderweb strung between two dead twigs. Beyond the stone, the path she had followed from the last public gate had vanished. Not grown over. Not forked. Vanished. One minute there had been a deer track pressed into mud beneath skeletal branches; the next, only grass, waist-high in places, beaded with frost though the night was not cold enough for it.
She turned and looked back.
Behind her, the park was gone too.
No distant orange smear of London. No hum of traffic from the road. No plane lights blinking above, no far-off siren, no drunk laughter carried from some path where ordinary people made ordinary terrible decisions. Just trees, too many and too still, their trunks crowding in uneven ranks. The sky hung overhead in a narrow black bowl pricked with stars she did not recognise.
Rory swallowed.
She had come here for a reason. That was the rope she kept hold of, the fact she could wind around her fist and pull herself forward with. She had not gone wandering into a hidden Fae-touched grove at night because she fancied an atmospheric breakdown. The message had been waiting beneath her flat door when she returned from the Golden Empress, feet aching, hair smelling faintly of sesame oil and rain.
If you want to know why the Heartstone burns, come to the oak stones in Richmond when the moon is blind.
No signature. No explanation. Just the words, inked in a hand too neat to be friendly.
She had done the sensible things first. She had sworn. She had made tea. She had considered ignoring it. Then the pendant at her throat had warmed until the skin beneath it flushed red, and the deep crimson stone had begun to pulse like a second heart.
It had not stopped until she put on her jacket.
Now it lay under her jumper, small as a thumbnail, warm against her sternum. Not burning. Not yet. A faint inner glow bled through the weave when she angled the torch down, a dull red ember breathing beneath black wool.
Rory hooked one finger under the silver chain and lifted the Heartstone free.
The pendant looked prettier than it had any right to look in a place like this. Crimson, faceted but not cut in any human way, with depths that seemed to fold inward rather than reflect out. Its warmth kissed her fingertips. A pulse . Pause. Pulse.
“Fine,” she said softly . “You got me here.”
The stone pulsed again.
The standing stone ahead of her answered.
Not with light. Not exactly. Its surface darkened, as though the moonlight had been sucked into it. For a moment Rory saw markings under the lichen: long, hooked lines like claw marks, spirals within spirals, a shape that might have been an eye if she stared long enough and had no interest in sleeping ever again.
Then the torch flickered .
Rory smacked it with the heel of her hand. The beam steadied.
Somewhere beyond the stone, a twig snapped.
She went still.
The sound had been small, precise, close enough to belong to a person shifting their weight . Her first stupid thought was deer. Richmond Park had deer. Everyone knew that. Red deer, fallow deer, picturesque as postcards until they stepped out in front of a car. But the thought did not settle. Deer made noise in the undergrowth. They snorted, grazed, moved with nervous bursts.
This had been deliberate.
Rory lifted the torch and swept it slowly left to right.
The beam caught tree trunks, silver grass, a cluster of wildflowers blooming impossibly bright at the base of a holly bush. Bluebells in January. Foxgloves with white throats speckled purple. Buttercups open under starlight. They did not move in the faint wind because there was no wind.
At the edge of the light, something pale slipped behind a tree.
Rory’s chest tightened.
“Hello?”
She hated herself the moment she said it. Every horror film victim in history had at least had the decency to ask it in an American accent. Her Welsh vowels made it worse somehow, more personal. Hello? Are you there, unspeakable woodland nightmare? Lovely night for it.
Nothing answered.
The torch beam trembled despite her best efforts. She forced her hand steady and moved it back to the tree where the pale thing had gone. The trunk was thick, bark furrowed deep. Behind it, darkness pooled.
“Eva, if this is somehow you taking the piss, I will actually murder you.”
The grove swallowed Eva’s name without echo .
Rory listened.
At first there was only her breathing. Then, under it, another sound surfaced.
A drip.
Slow and regular.
Drip.
Pause.
Drip.
Water, maybe. From branches. Rain caught in leaves. Sensible. Except it had not rained since late afternoon, and the trees around her were bare-limbed oaks and hornbeams, their branches thin as black fingers.
Drip.
It came from beyond the first stone.
Rory looked at the pendant. The Heartstone warmed by a degree.
“Of course it does.”
She stepped past the standing stone.
The air changed.
It pressed against her eardrums like a train entering a tunnel. Her skin prickled beneath her jacket; the small crescent-shaped scar on her left wrist gave a sharp, ridiculous twinge, as if childhood itself objected to the decision. She flexed her fingers and kept walking.
The grove unfolded where no grove should have fit. One step through the stones and the crowded trees opened into a wide clearing ringed by ancient oaks, their trunks vast and twisted, their branches laced overhead in a broken dome. More standing stones marked the boundary, some leaning, some half swallowed by moss, each one shaped with that same unnerving suggestion of petrified wood.
Wildflowers carpeted the ground. Not scattered patches, not brave little clumps, but a dense living quilt of colour: red poppies, white stars of stitchwort, yellow primroses, violet pansies, flowers Rory could not name and did not want to. They bloomed year-round here, if the stories were true. They gave off a scent too sweet for winter, honey and damp earth and something rotten underneath.
In the centre of the clearing stood a single flat stone, waist-high, like an altar.
Rory stopped at the edge.
The dripping came from there.
Drip.
The altar stone was dry.
Drip.
Nothing fell.
Her mouth had gone dry enough to hurt. She tried to count exits, because panic liked vagueness and she liked numbers. There were the gaps between stones. Twelve? No, thirteen. No—when she looked again, eleven. The oak trees overlapped in ways that made her eyes slide away. The route she had used to enter was behind her, surely; she had kept the first stone at her back, had walked straight. She glanced over her shoulder.
There were three stones there now, all identical.
Rory’s pulse climbed.
“Right,” she whispered. “That’s rude.”
The Heartstone pulsed hard enough to tug the chain.
She looked down.
The crimson gem glowed brighter, not with reflection but with interior fire . Warmth spread against her palm. It pulled—not physically, not like a magnet, but with a certainty that settled behind her ribs and angled her toward the altar.
That was the reason. That was why she had come. Find out why the pendant burned. Find out who had sent the note. Find out whether the thing around her neck was a gift, a leash, or a beacon .
She crossed the clearing.
Flowers bent away from her shoes. Not crushed. Bent. Primroses dipped their yellow faces. Foxgloves turned inward. The grass parted as if something under the soil inhaled. She watched each step and refused to look at the oak line where she could feel , with increasing certainty, eyes.
Halfway to the altar, a laugh sounded behind her.
Small. Breathless. A child’s laugh.
Rory froze.
The skin between her shoulder blades pulled tight.
No.
Children did not laugh alone in hidden groves after midnight. Children were home in bed or refusing to be in bed, arguing for water, another story, five more minutes with a tablet. They were not here.
The laugh came again, further left.
A little girl’s giggle, bright with mischief.
Rory did not turn all the way. She moved only her eyes first, then the torch, then her shoulders. She knew better than to whip around. Knew, though she could not say how, that sudden movement would be taken as invitation.
The beam slid over flowers and black trunks.
At the base of one oak stood a child in a pale dress.
Rory’s heart gave one hard slam.
The child was half hidden behind the trunk, only one shoulder, one bare foot, and half a face visible. Her hair hung long and dark over her cheek. She was too far away for Rory to see her eyes, but Rory knew they were fixed on her.
“Are you lost?” Rory asked.
The words came automatically, absurdly. Practicality was a stubborn weed in her. If a child was in front of her, she asked if the child was lost, even if every instinct in her body had begun screaming.
The child leaned farther around the tree.
Her visible mouth smiled.
Too wide.
Rory’s grip on the torch tightened until the plastic creaked.
The child lifted one hand and beckoned.
One finger curling. Come here.
“No,” Rory said.
The smile did not change.
A second laugh sounded from behind another tree. Then another. Not echoes . Different voices. Children giggling in the dark all around the grove, hidden among the oaks, delighted by a joke only they understood.
Rory backed up one step toward the altar.
The giggles stopped together.
Silence hit so completely she heard the blood in her ears.
Then came a whisper, close to her left.
“Laila.”
Rory spun.
The torch beam slashed through empty air.
No one stood there. Only flowers, their faces tilted toward her as if listening .
Her breathing had turned shallow. She forced it deeper. In through the nose, out through the mouth. Panic wasted oxygen. Panic narrowed options. Panic had kept her in Evan’s flat too long, once upon a time, measuring the weather of a man’s voice instead of the distance to the door. She had learned since then. Fear was information, not instruction.
No one in London should know that name .
Laila was not a name she used at the Golden Empress, not a name Silas called up the stairs, not one from Cardiff, not one her father had ever put on legal documents. It belonged to stranger circles, stranger problems. If the grove knew it, then the grove was listening in places it had no right to hear.
“Who sent the note?” Rory said.
Her voice came out steadier than she felt.
The oaks did not answer.
The altar was three steps away now. Its top looked slick in the torchlight, though when she angled the beam, no liquid shone. The drip continued beneath the silence .
Drip.
Pause.
Drip.
On the stone lay an object that had not been visible from the edge of the clearing.
A key.
Old iron, long-shanked, with a bow shaped like two antlers branching from a skull. It rested on a square of folded paper. Rory stared at it for several seconds, unwilling to move closer, because objects placed on altars in hidden groves were rarely free samples.
The Heartstone flared.
Heat bit her palm. She hissed and dropped it. The pendant swung against her chest, burning through her jumper.
At the same instant, the dripping stopped.
Every flower in the grove turned toward the altar.
Rory saw it happen. Poppies twisted on delicate stems. Bluebells lifted their bowed heads. Foxgloves opened their spotted throats. Hundreds, thousands, all orienting silently toward the flat stone and the iron key.
Then something breathed behind her.
It was not close like the whisper had been. It was vast. A deep, slow draw of air from the oak line, as if the forest itself had discovered lungs.
Rory did not turn.
Her bright blue eyes fixed on the key. The torch beam shook over it. She could smell cold metal now, sharp as blood in the mouth, and beneath that the sickly sweetness of flowers.
A shape moved at the edge of her vision.
Tall.
Not human tall. Not deer tall. A vertical absence sliding between two oaks, jointed wrongly, crowned with branching darkness. Rory’s mind tried to make sense of it and failed with a sensation like slipping on stairs. Antlers, it offered. Branches. Arms raised overhead. Anything but what stood there.
She kept her gaze on the altar.
“Right,” she said, almost silently. “I take the creepy key or I get eaten by shrubbery. Choice architecture could use work.”
The thing among the trees exhaled.
The flowers rippled without wind.
Rory moved.
She snatched the iron key and the folded paper in one hand, expecting cold, expecting heat, expecting pain. The key was neither warm nor cold. It felt dry and rough, like bone left in a drawer for years. The paper crackled against her palm.
The moment her fingers closed around them, the grove changed.
Not dramatically. No thunder, no shriek, no split in the earth. That would have been easier. Instead every sound resumed at once but wrong: the drip became a clock tick; the children’s laughter became leaves rubbing together; the leaves became whispers; the whispers became her name.
Aurora.
Rory.
Carter.
Laila.
Malphora.
The last name struck the clearing like a stone dropped into deep water.
The Heartstone blazed red.
From the far side of the altar, where there had been only flowers, a seam opened in the air.
Rory’s vision doubled. The clearing remained: oaks, stones, flowers, night. But overlaid on it, through a narrow vertical wound, she saw another place. Black rock. A sky the colour of bruised meat. A field of ash where something moved beneath the surface in slow, restless waves. Heat rolled out, dry and ancient, carrying the stink of sulphur and extinguished candles.
The pendant pulsed against her chest in a frantic rhythm.
Near a Hel portal, then, the thought came with horrible clarity. That was what it did. Warmed near a Hel portal.
Not Fae.
Not only Fae.
The seam widened by the width of a finger.
The tall shape at the oak line inclined its head.
It had no face that Rory could see, but she felt its attention sharpen. The child-things giggled once, all together, then fell silent.
The paper in her hand fluttered though there was still no wind.
Rory looked down.
One word had been written on the outside in the same neat hand as the note.
Run.
“Now you tell me.”
The seam widened again.
Something on the other side pressed close. Not emerged. Not yet. Pressed. The air bulged inward as if invisible glass separated the grove from that ash-black place, and something enormous had leaned its weight against it. Rory heard a low scraping, like nails dragged along stone miles below ground.
She bolted.
The grove did not want her to leave.
Flowers tangled around her ankles. Grass slicked underfoot. The altar seemed to lurch sideways in the corner of her eye, though she knew stone did not move. She aimed for the gap she thought she had entered through, the one between two leaning oak-stones, and sprinted with the key biting into her palm.
Behind her, the children began to laugh again.
Not giggle. Laugh. High, breathless, delighted.
“Rory,” one called in Eva’s voice.
She nearly stumbled.
“Rory, wait!”
No.
She ran harder.
The gap between the stones stretched away. It had been twenty feet. It became thirty, then fifty. The ground dipped where it had been flat. Her lungs burned. Her shoulder-length black hair whipped against her face, damp with sweat at the temples. The torch beam bounced wild over stone and bark and brief pale faces peering between trunks.
A hand brushed her sleeve.
Small fingers. Cold as pond water.
Rory swung the torch without looking. It struck something soft and light. The laughter beside her cut off with a hiss.
“Do not touch me.”
Her voice cracked across the clearing, fierce and raw.
For one instant, everything recoiled.
She reached the stones.
They stood closer together than before, the gap between them narrow as a doorway. Lichen writhed over their surfaces like slow green veins. Beyond them lay darkness, ordinary darkness perhaps, the park perhaps, or another trap wearing the shape of escape.
Rory did not slow.
The Heartstone burned.
The key pulsed in her fist.
The thing behind her screamed without a mouth.
Sound slammed into her back and drove her between the stones. The air turned solid around her, squeezing ribs, skull, throat. She tasted copper. For one terrifying second she was nowhere—no grove, no park, no body, only red light and the sensation of being noticed by something vast beneath the world.
Then she hit mud on hands and knees.
Cold night air rushed into her lungs.
Traffic hummed somewhere far away.
Rory stayed on all fours, coughing, her palms sunk in wet earth. Her left wrist throbbed where the crescent scar gleamed pale under a smear of mud. The torch lay beside her, still lit, pointed at a crushed takeaway coffee cup near the path.
Richmond Park stretched around her, dark and damp and blessedly ordinary. Bare trees. Winter grass. A distant city glow pressing low against the clouds. Her phone buzzed in her pocket so suddenly she flinched.
She dragged it out with shaking fingers.
The screen showed 12:17 a.m.
She had entered the grove at 12:14.
Three minutes.
Her legs trembled as she pushed herself upright. Behind her, there was only an old oak tree and a scatter of stones half hidden in brambles. No clearing. No flowers. No seam in the air.
No children.
Rory opened her hand.
The iron key lay across her palm, black and real, its antlered bow crusted with something that was not rust. The folded paper clung beneath it. Slowly, she unfolded the note.
Only one line waited inside.
You were not the first to carry it.
The Heartstone, cooling at last, gave one faint pulse against her chest.
From somewhere deep among the trees, a child laughed.
Rory folded the paper with careful, shaking precision and put the key in her pocket. She did not run this time. Running gave things permission to chase.
She picked up the torch, turned toward the distant road, and walked, every nerve straining toward the darkness at her back.
Behind her, in the park where no wildflowers should have bloomed, something began to drip.
